Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

A unified model for microstructure-sensitive fatigue crack initiation across low and high cycle fatigue

Materials & Design
Microstructure-sensitive modeling has shown promise to reduce reliance on experimental test campaigns to determine fatigue performance. However, most existing fatigue life models use metrics focused solely on fatigue crack initiation (FCI), but which are
